Autonauticinstrumental - B+C Compensation Kit for C20 Compasses

Assembly and Operation of the Compensation Kit

• The distance from any magnetic influence must be at least 50 cm.
• The compass should be installed outside of a closed environment of magnetic iron as this will shield the terrestrial field.
• The compass must be installed at a sufficient distance from the influence of any magnetic field: main engine, windscreen wiper motor, extinguisher, other compasses, speakers, etc. Any magnetic disturbance can affect the compass. Furthermore, magnetic fields are variable and variable fields cannot be corrected in principle.
• Unscrew the two screws and remove the U-shaped cover to open the correction system.
• Each corrector contains two magnets, which can be inserted into the different holes. The side marked in red of the magnets in one direction will have an opposite deviation to the red side in the other direction. The number and distance of the magnets from the directional system determine the magnitude of the deviation. A distant position will cause a smaller deviation.
• One can fix the device horizontally, vertically, or in between; this will make no difference.

Important

It is necessary that the magnets are finally oriented exactly fore and aft of the vessel. The C-corrector device for adjusting the permanent field to windward must be fixed or aft of the compass. It is necessary that the magnets are finally oriented exactly to windward of the vessel. A correct adjustment is essential for safe and reliable navigation. It is necessary that the adjustment is carried out by a qualified compass adjuster.
